Aerofficient has announced that production of its Slider side fairing for on-highway trailers will begin in April. According to Aerofficient, the patent-pending system automatically expands or contracts when the trailer’s axles are moved, filling the gap between the trailing edge of a standard “fixed” trailer side fairing and the trailer’s tires.
At a typical 41-ft. axle setting, there is a gap of 30 to 40 in. between the fixed fairing’s trailing edge and the trailer’s front tire, Aerofficient says. Testing with a 35-in. gap against multiple competitors’ standard fixed fairings in highway SAE Type IV tests, the Aerofficient Slider generated 7.2 percent savings compared to 3.8 percent to 4.2 percent for competitors’ standard fixed fairings, the company says.
All Aerofficient side-fairing products use a patent-pending clamp system for fast installation without the need to drill holes in the trailer, the company says. Aerofficient says the new Slider fairings can be installed with its fixed fairings on new trailers, or added to units with existing Aerofficient fixed side fairings.
